CausesofInvalidParameters:

Invalidparameterscanbecausedbyavarietyoffactors,includingincorrectinputfromtheuser,programmingerrors,andproblemswithdataformatting.Invalidinputcanincludeanythingfromincorrectdatatypestomissingparameters.Programmingerrorscanoccurwhenthecodeiswrittenincorrectlyorwhentherearelogicerrorsintheprogramthatcauseinvalidparameterstobepassedtofunctionsormethods.Dataformattingissuescanarisewhendataisnotproperlyformattedorwhenincorrectdataisenteredintoaprogramorsystem.

AvoidingInvalidParameters:

Thereareseveralstepsthatcanbetakentoavoidinvalidparameters.First,inputvalidationshouldbeusedtoensurethattheuserentersvalidinput.Thiscanincludecheckingforthecorrectdatatype,range,andformat.Second,testinganddebuggingshouldbeusedtoidentifyandfixprogrammingerrorsthatcanleadtoinvalidparameters.Finally,datashouldbeproperlyformattedandvalidatedbeforebeingenteredintoaprogramorsystem.

Conclusion:
